Application of Automatic Detection System of Unit Air Gate Displacement in Hydroplants
Aiming at the problems of installation and debugging difficulties of conventional mechanical travel switch and inadequate action of air gate travel switch,an actual hydroplant adopted the proximity switch based on Hall sensor princi-ple for replacement and retrofit,and developed an automatic detection system that can collect the unit air gate status and monitor its displacement.The automatic detection system collected the state and displacement of the air gate by PLC,made logical judgment,and used the intermediate relay to the monitoring system of the hydroplant and the brake control screen of the unit.At the same time,the stroke displacement of the air gate was transmitted to the background of the mo-nitoring system for status monitoring.
